Turning IPv6 on at the basic/core of the infrastructure is the easiest part of the job. However turning IPv6 for customers requires a lot of effort and compromises. Some of the reasons are described in: http://6lab.cz/article/deploying-ipv6-practical-problems-from-the-campus-perspective/ and related presentation: http://6lab.cz/wordpress/wp-content/uploads/2012/05/tnc2012_slides_TncPresentation.pdf We (Internode), an Australian ISP, have native dual-stack enabled by default (and have done for a while) for almost all new broadband services (ADSL, FTTH, etc.). Our existing customers can turn it on via an online toolbox. All the broadband CPE that we sell, support it. It's largely a non-issue for us now. Most new customers running a 'current' operating system, who buy an ADSL or FTTH service and their modem/router from us, automatically get IPv6 from day dot without even necessarily realising it.

Why do you think Google's numbers are lower than the real total? It depends on what you are trying to measure and how you are measuring it. I don't know Google's methodology, but lets say its a simple form of the experiment: When presented with a dual stack object what percentage of users prefer to retrieve that object using IPv6 as compared to IPv4? Up so a year or so ago if a browser had access to IPv6 and IPv4 it would first attempt to connect using IPv6 and if the connection failed then it timed out and then tried to use IPv4. So the experiment would be roughly commensurate with measuring working IPv6 systems on end sites connected to workin ipv6 access networks of one sort or another. More recently some browsers (Safari on Mac OSX, Chrome, Firefox with config settings enabled) have adopted a different strategy and when presented with a dual stack object some clients may end up trying the connection using IPv4 first and then fall back to IPv6 if IPv4 fails or times out. If the experiment simply counts the percent of clients who prefer to connect using IPv6 in a Dual Stack scenario, then some of these users running more recent versions of the browser will not be counted. There are ways to compensate for this, including running a series of tests, and this form of approach is described at http://labs.apnic.net/measureipv6/ I personally have no knowledge if the numbers published by Google reflect the prefers to use IPv6 in dual stack mode or is capable of using IPv6 (by virtue of being able to retrieve a IPv6 only object) These days the second number is larger than the first.

If you do follow that on vm's (which can actually be a good practice), make sure they pull from your own time infrastructure, and not just the world at large, and that those servers behave in a sane fashion with regard to time jumps. Emphatically disagree on the pull from your own infrastructure point. You probably don't have the budget even in a big company for sufficient diversity of sources [*] for your NTP server and even if you do the NTP servers will probably be run by the same person/organization. Mills has called the latter practice out as bad in the past. As Leo pointed out, the key is having a large diverse set so that if a couple of them go nuts they can be voted off the island. If you have a requirement for super low jitter or holdover if you lose network, you're looking at on-site devices with OCXO or Rb frequency standards in them. That doesn't mean you shouldn't be talking to the rest of the world too though. What if your on-site sources go nuts?

It won't. Users do not care about IPv6 or IPv4. They want a fast and reliable Internet connection. If you think you can do that with IPv4, you don't need to do anything (well, just plan for some budget for your CGNs). If not, better start deploying IPv6. .as On 21/11/2012 12:40, Joe Maimon wrote: I have had approximately 0.01% interest from any user base. That would be an interesting number to watch change.

Does the NTP code, people who know, give any extra credence to strat-1 sources in it's byzantine code? Not in a way that matters if one of them suddenly becomes a falseticker. If a reference clock goes insane, it's pretty easily detected provided you have at least two more servers (or even peers configured.) Stratum 1 just means it thinks it has a reference clock attached, but those clocks fail, go into holdover, what have you all the time.

A first thought would be an adjacent country, but maybe there is a benefit to picking things outside of the pool.ntp.org selection entirely? First of all: None of the ~3800 servers in the NTP Pool system were affected by this as far as I can tell from the (copious) monitoring data. The big benefit to adding some non-pool servers is that you wouldn't be depending basically on a bunch of volunteers (and to a large extent me) for your time keeping. Though likely you'd just be depending on another group of volunteers. In addition to depending on the server operators who run the ntpd servers you also depend on: 1) The monitoring system keeping accurate time. 2) The monitoring system does its job catching bad servers. 3) The process updating and distributing the DNS data working. 4) The DNS servers working (and not being under a DoS attack or similar). 5) Anything I haven't thought of! Empirically I believe we've done a better job than just about anyone with a similar scale, but past performance is no promise of the future. I see that Jared used *.fedora.pool.ntp.org -- I wonder if there was a specific reason for that or if my questions are even worth thinking about at all :-). The servers for x.fedora.pool.ntp.org are in the same group as x.pool.ntp.org. If you are in a country with many servers in the pool then you'll very likely get different IPs for the two. If you are in a country with few servers your odds for that aren't so good and it'd be a bit pointless. Anyone using the NTP Pool in a default configuration (like Fedora does) must get a vendor zone setup - http://www.pool.ntp.org/en/vendors.html - so we have at least a little bit of a chance to monitor and mitigate problems. It also allows us to change what servers are selected, how many IPs are returned etc for a particular vendor. For example if Fedora in the future changes to use 'pool' instead of 'server' in the configuration we could optimize for that. Ask -- http://askask.com/

I have some questions regarding some H3C Switch spanning-tree behaviour, but I can't find anyone to ask. The couple of lists on puck have had almost no traffic for a ling time.
